  • Good guess about the federating problem. Thats a good reminder for me to change instances (was on lemm.ee before it died, .world was my backup).

    OTA, While a fair point, again is a technical problem. Desktop systems get timely OTA updates. Its perfectly possible for rooted Android to get security updates that are on-par with rooted (e.g. basically any) Linux systems. The hash can be done on the incoming update instead (integrity hash) instead of on the system.

    Linux has other tools and protections.

    1. If there are protections they’re at the system level (not app space). Which means the ROM provider could/should add those same protections as Linux instead of saying “you dont need root, stop asking”.
    2. AFAIK there are, unfortunately, basically no protections on Linux. Sudo can be trivially shimmed (add malicious exe to PATH) without even having sudo permissions, then the next time user inputs sudo an attacker would have their password. Its bad that its so easy, but its a double standard to say Linux is fine but an (up to date) Android with root is vulnerable.






  • Additionally (I still love roundabouts) there can be a max-wait-time problem when there is heavy traffic in one direction.

    If a basketball game ends there can be 20,000 cars bumper-to-bumper trying to leave. Let’s say (looking at a map) they’re going left-to-right through an intersection.

    If there’s 1 car trying to go top-to-bottom…

    • If the intersection is a stoplight it doesn’t matter. Even if there were 20 million left-to-right cars; it’s still a 5 or 10min wait for the top-to-bottom car.
    • If the intersection was a stop sign it also doesn’t matter; it’ll be the left-to-right cars turn then the top-to-bottom cars turn
    • At a roundabout though (at least in the US), vehicles entering on the left always take priority over vehicles entering from the bottom. So the top-to-bottom guy could be there all night

    Game days on my campus can cause a 2 hour wait on a 1 mile road. My campus is unusual, but just FYI absolutely insane wait times do happen regularly in some cities.
